Where are the generated fixtures stored?

The skill writes the generated JSON files directly into the project's designated fixtures/ directories for immediate use.

What schemas does this skill support?

It currently targets CommandDTO and DecisionDTO schemas typically found in the contracts/schemas directory of the project.

Does it integrate with existing testing tools?

The generated fixtures are designed to be consumed by contract-checker and graph-sanity testing utilities.

Can it generate data for negative testing?

Yes, it specifically generates invalid scenarios including missing required fields, ambiguous shapes, and incorrect enum values.

セキュリティとテスト

Generates valid and invalid JSON test fixtures for Command and Decision DTOs based on current contract schemas.

概要

The Fixtures Generator skill automates the creation of canonical test data for contract validation and graph testing. By analyzing schema definitions for commands and decisions, it produces both minimal valid examples and purposefully invalid scenarios—such as missing required fields or incorrect payload shapes. This ensures that testing suites like contract-checker and graph-sanity have robust, up-to-date data to verify system integrity against evolving contract versions.
